(2) 3AD-□□□V(CRM-V) The shipping package should contain one adapter and four installation bolts (hexagon head).① Remove the side cover installation bolts, followed by the side cover.
(See Fig. 9) ② Remove the bolts (with seal washer) which secure the side cover and
wire screen weight (for V□1, outer cylinder of the cover) (See Fig. 9) ③ Tighten the hexagon head bolts together with - in the order of - the
adapter, side cover, wire screen and wire screen weight (for V□1, the outer cylinder of the cover) so that the packing installation face of the adapter is the matching face of the side cover. (Attach the seal washer that was with attached to the removed bolts) (See Fig. 10)
④ Attach the side cover with the bolts.

3. After-filter and inner-filter (sold separately) installation guide<Installation procedure>
Place the packing over the adapter (sold separately), then use the wing nut to secure the after-filter.
<Installation cautions>Always tighten the wing nut by hand only. The after-filter already has filter cases A and B, and a filter element installed. When replacing the filter, it is only necessary to order the filter element. The adapter and inner filter are sold separately.
[Note] The 3AF-41E filter case "A" and the adapter are integrated (single component), and an adapter is therefore not required. For installation procedure details, refer to the dedicated installation/operation guide.
<Replacement procedure>Removal ..... Loosen the wing nut at the upper part of filter case "B", then
extract filter case "B" and the filter element by lifting them upward.
Installation ... Center the filter element on filter case "A". Place filter case "B" on top, then tighten the wing nut.
<Inner filter>After-filter clogging may be accelerated in areas with large amounts of oil mist and oily smoke. The rate of clogging can be slowed by installing the inner filter (sold separately) inside the filter element.
[CAUTION] The after-filter and inner-filter cannot be reused even if washed.

<Installation procedure>① Loosen the 4 nuts which secure the Mistresa's duct phase flange, then
remove the duct phase flange (see Fig.12). ② Secure the chip separator adapter to the Mistresa using the 4 nuts
which had been used to secure the duct phase flange (see Fig.13) .(Fig.14 shows the proper orientation for the chip separator adapter.)

5. Chip separator installation guide(1) 3CS-□□□, 3CS-□□□M (CRD(-H), CRH(-H), CRN, CRM(H)-S)
A chip separator, drain tube (2.5m), and hose band packing have been shipped together with the accessory item. Installation bolts and nuts (4 sets) have also been provided.
<Installation procedure>① Loosen the Mistresa's duct companion flange stops (4 locations), then
detach the duct companion flange.(On models CRD-H and CRH-H, the duct phase flange is removed when installing the chip separator adapter.)
② Release the chip separator's corner clamps (2 locations), then extract the filter with frame.
③ Position the chip separator's chip outlet port toward either the left or right, then insert a packing between the chip separator and the Mistresa and secure with bolts (the chip separator's front and rear mounting holes are the same size).
④ Place the duct companion flange (with packaging) which was detached from the Mistresa, then secure with bolts and nuts. (For the CRH series, insert packing between the duct companion flange and the Mistresa.)
⑤ With the wire screen side positioned at the downstream (main unit side), insert the filter with frame into the chip separator, then attach the cover. (For 3CS‒□□□M, attach the cover to face the clogging status indicator as shown in Fig. 16 on page 8.)
⑥ Insert the drain tube into the drain pipe, then secure it with the hose band. Take care to avoid bending the drain tube, and be sure to seal (liquid seal) its end.
<Chip ejection procedure>Release the upper and lower corner clamps in that order, then discharge the chips. Because drain matter such as cutting oil, etc., is also present inside, hold a cloth against the bottom of the cover before opening it to prevent spillage and soiling.

<Clogging status indicator for 3CS-□□□M>3CS-□□□M is equipped with a clogging status indicator. This section explains how to read the indicator, and how to make the initial setting.
① Reading the clogging status indicatorAs shown in Fig.16, the float position should be checked when the power is turned ON.The upper part of the float is red and the bottom part is green. When the filter is in good condition (not clogged), the float's green part is visible. When clogged, the red part is visible.
② Initial settingThe initial setting described here assumes that the Mistresa is in a standard operating condition (3m or less from the suction duct, with no after-filter installed at the discharge side). Depending on the customers piping configuration and installed accessories, the following initial settings may be required.a Loosen the Fig.16 nut. b Adjust the Fig.16 bolt as follows:
When an after-filter is installed …… Loosen the bolt 1/4 of a turn.When the distance from the suction side is greater than 3m …… Tighten the bolt 1/4 of a turn.If other special piping exists …… Tighten or loosen the bolt until
the float sinks (drops), then loosen the bolt 2 turns from that position.
c Secure the bolt, then tighten the nut. (Both the bolt and nut have right-hand threads.)
③ Note When the resistance changes within the pipe on site, the clogging status indicator may not operate properly. In particular, if the wire screen is installed on the inspiratory side, the screen could get clogged and malfunction, so we advise not installing anything that could cause clogging as far as possible.

(2) 3CS-□□□V (CRM-V)The shipping package should contain one chip separator and four installation bolts.
<Installation procedure>① Overlap the chip separator’s face without the drain pipe and the bottom
of the Mistresa, then secure with bolts. (Nuts are welded onto the chip separator side.) Ensure that the chip separator's chip outlet port is facing the same direction as the filter box slot of the Mistresa.
② Secure the Mistresa with the chip separator with bolts from the machine and equipment side. (Nuts are welded onto the chip separator side.)
<Chip ejection procedure> Release the corner clamps, then discharge the chips. As drain matter such as cutting oil, etc., is also present inside, hold a cloth against the bottom of the cover before opening it to prevent spillage and soiling.

6. Air suction adapterThe shipping package should contain an air suction adapter, two drain tubes (2.5 m), two hose bands and four bolts.
<Installation procedure>① Overlap the air suction adapter with no packing face and the bottom face
of the Mistresa, then secure with bolts. (Nuts are welded onto the air suction adapter side)
② Secure Mistresa with the air suction adapter with the machine and equipment side using bolts and nuts.
③ Insert the drain tube into the drain pipe and secure it with the hose band. The end of the drain tube should be exposed to the atmosphere without being bent.
7. φ15 Drain tube unitThe shipping package should contain two φ15 drain tubes, two hose bands and two hexagon hose nipples (with seal tape).
<Installation procedure>① Connect the hexagon hose nipple to the drain pipe on the Mistresa.② Insert the drain tube into the hexagon hose nipple, then secure it with
the hose band. (As for the piping configuration of the drain tube, see the Piping section of the Operation Manual & Cautions of the Mistresa.)
